SPECIFICATION forming part of Letters Patent No. 528,415, dated October30, 1894. Application filed A ril 21.1893. Serial NoA'ILBBO. (liomodel.)

To all whom it may concern:

Be it known that I, JOHN DANIELSON, a sub- King of Sweden and Norway, ana resident of Alhambra Springs, county of J c ferson, State of Montana,have invented a new and useful Improvement in Saws, of which thefollowing is a specification.

Long saws are necessary for use in cutting up the large trees utilizedin lumbering, &c., and several inventions have been made to enable oneman to advantageously use them. In most cases more or less machinery isused.

My invention supplies a saw and simple frame that enables one man tohandle, successfully, the longest saw necessary, with ease and in allpositions.

It consists of a wooden spring pole,having a steel stiifening spring atthe center, and sprung upon the saw blade by means of metal sockets.

Figure I shows side elevation of whole apparatus. Fig. II shows planview of steel spring. Fig. III shows end elevation of clip for holdingspring. Fig. IV shows perspective of end socket. Fig. V showsperspective of handle socket.

Similar letters refer to similar parts in all the drawings.

The metal end-socket A end of the saw B by means of the slot at and bolt1). The metal handle-socket G is likewise attached to the saw B, bymeans of the slot 0 and bolts (1 d, and is bent into a U shape toreceive the wooden handle D. Into these sockets A and G are sprung theends of the spring pole E. Attached to the under side of the spring poleE by means of the clips F F, is the steel spring clips F F are held inposition by the screws f f. On the upper side of the spring G are twosmall lugs or flanges g g which embrace the pole E and prevent thespring G from slipping sidewise. One end of this spring G is threadedand carries the nut It. By screwing this nut it against the clip F, thespring may be tightened. The advantages of this spring frame are many.

is attached to one 4 It allows one man to use the usual two-man saw withease. The trouble of vibration,common to one-man saws, is entirelyobviated. The usual thickening of the back to stiifen the saw isunnecessary, and a very thin saw may be used, thinner at the back thanat the cutting edge and having very little set. It is easily carriedthrough the timber, and the bow affords a new handle when the cut isdeep in the log, thus doing away with much stooping. In case of breakingo the bow, a new one can be readily adjusted. In case of pinching of thelog above the saw, no wedges need beused, as the end bolt can be quicklyremoved and the saw withdrawn through the cut.

and by the addition of the steel spring, keeps the necessary tension fora long time.

With this simple mechanism, one man can cut nine cords of wood in thetimber, in the same time and with greater ease than the same man can outthree cords, with the ordinary one-man saw.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a saw, the combination of the sawblade and the spring frame,-with the metal stiffening spring, placedcentrally on the under side of the frame,substantially as shown anddescribed.

2. In a saw, the combination of the saw blade and the spring frame, withthe metal stiffening spring fastened to the frame by the clips ff andhaving the lugs g g and one threaded end carrying the nut h,substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 7th day of April,

JOHN DANIELSON.
